Answer:
16
Step-by-step explanation:
Shape C is A trapezoid
Area of trapezoid = [tex]\frac{a+b}{2} h[/tex]
where a and b = base lengths and h = height
The trapezoid has the following dimensions
base 1 = 3 units
base 2 = 5 units
height = 4 units
Using these dimensions we plug in the values into the formula stated above.
[tex]A=\frac{3+5}{2} 4\\3+5=8\\\frac{8}{2} =4\\4*4=16[/tex]
Hence the area of shape C = 16 square units
Answer:
rectangle A's area: 12, 3 x 4 = 12
Area b: 1 x 4 = 4 divided by 2 = 2, the base is 1 height is 4. Multiply given lengths, then multiply by 1/2 because formula of a triangle is BH x 1/2. To get your answer of 2.
Area C: 3 + 5 = 8, 8 x 4 = 32, 32 divided by 2 = 16, formula of a trapezoid is base 1 + base 2 x height x 1/2. In this case 5 is your base and base 2 is 3. Add them up to get 8. We then multiply 8 by the height which is 4 if you count from the top to bottom in the middle. 8 x 4 = 32. 32 x 1/2 = 16 (basically just dividing by 2).
